matrix indexes

[tal23]

I wanted to use matrixs in awk and got some problem, here is some of the script code, from the BEGIN tag:

row_char[1]="a";row_char[2]="b";row_char[3]="c";row_char[4]="d";row_char[5]="e"$
row_char[8]="h";row_char[9]="i";row_char[10]="j";row_char[11]="k";
# from the proccess passage:
sentence[varchar[11],1]=1;
diffrence=4;
i=7;
sum_index=diffrence+i;
printf("test: %d",sentence[row_char[11],1]); # it prints that like it should be test: 1
printf("test2: %d",sentence[row_char[sum_index],1]); # here it prints test2: 0 that does not right.

I almost sure the problem is the form of the array index ,as in awk probably there is no matrixs.
Please help me with this.

Hi tal23! Welcome to bytes.com!

It's great to have you here!

When you post, please always keep to the Posting Guidelines and when you post code, please post it in [code] ... [/code] tags. In this case I added them for you - your question was very difficult to read without them.

I'm sorry to say, that I can't help you with your question, but I'm sure someone will.

Otherwise, I'll just wish you the best and hope you enjoy being part of bytes.com!

That is only a passages from the script but it can run like a script even in this shape.
the important part from the begin passage:

BEGIN
{
row_char[1]="a";row_char[2]="b";row_char[3]="c";row_char[4]="d";row_char[5]="e"$ 
row_char[8]="h";row_char[9]="i";row_char[10]="j";row_char[11]="k"; 
}
# from the proccess passage: 
{
sentence[varchar[11],1]=1; 
diffrence=4; 
i=7; 
sum_index=diffrence+i; 
printf("test: %d",sentence[row_char[11],1]); # it prints that like it should be test: 1 
printf("test2: %d",sentence[row_char[sum_index],1]); # here it prints test2: 0 that does not right. 
}

The problem i need to solve is the value that been printed in the two printf sentences one showes a right result and one wrong but i must use the syntax of the second

Hi!
As I said before, please use the [CODE]...[/CODE] tags when posting code - just put the word [CODE] before your code and [/CODE] after it. Alternatively, use the # button in the message box. I've added those tags for you twice in this thread now.

Now, about your question: Try printing the value of sum_index - is it really 11, as it should be? I don't see any reason, why it shouldn't be, but you never know...

It has that value for sure.
